A needleless syringe for injecting an injection objective substance into an injection target area of a living body is provided. The syringe includes an enclosing unit enclosing the injection objective substance, and an ignition device including an ignition charge and flowing an ignition current so that the ignition charge is combusted. The syringe also includes a pressurizing unit pressurizing the injection objective substance, and a flow passage unit defining a flow passage so that the pressurized injection objective substance is allowed to inject to the injection target area. The pressurizing unit raises a pressure applied to the injection objective substance to a peak pressure for the injection objective substance to penetrate through a surface of the injection target area and then lowers the pressure applied to the injection objective substance to a waiting pressure within 2 msec after the ignition current was allowed to flow to the ignition device.

Syringe

The present invention provides an igniter assembly in which an igniter having an ignition portion and an electroconductive pin, and a metallic igniter retaining member are integrated with a resin molded article interposed therebetween, the igniter assembly, including: a connector insertion space formed by the resin molded article, the electroconductive pin being protruding from the resin molded article and located in the connector insertion space; a spark member including, a first end connected to the metallic igniter retaining member, and a second end, opposite to the first end, located inside the connector insertion space; and an electrically insulating partition wall having a thickness of 0.1 mm to 1 mm, provided with no through hole, and interposed between a root portion of the electroconductive pin, which is in contact with the resin molded article, and the second end of the spark member.

Igniter assembly for gas generator and manufacturing method thereof

It is possible to feed an injection objective substance to a depth of a skin structure of an objective living body without using any injection needle. A syringe having no injection needle comprises an enclosing unit which encloses the injection objective substance, a pressurizing unit which pressurizes the injection objective substance enclosed in the enclosing unit, and a flow passage unit which defines a flow passage so that the injection objective substance, which is pressurized by the pressurizing unit, is allowed to inject to an injection target area. The pressurizing unit has a first pressurizing mode in which a pressure applied to the injection objective substance in the pressurizing unit is raised to a first peak pressure in order to form a penetrating passage in the injection target area, and then the pressure applied to the injection objective substance is lowered to a waiting pressure, and a second pressurizing mode in which the injection objective substance having the waiting pressure is pressurized so that the pressure applied to the injection objective substance is raised to a second peak pressure to inject a predetermined injection amount of the injection objective substance.

An igniter assembly for which an igniter and a conductive igniter collar are integrated via an insulating layer, wherein the igniter comprises a metal eyelet, a metal cover that retains the eyelet therein, an ignition charge that is disposed in the cover and in a space in contact with an end face of the eyelet, a heating body that is connected to the end face of the eyelet, and a conductive pin that passes through the insulating layer and is electrically connected to the heating body. The other end of the conductive pin is exposed from the insulating layer so that a current supplying circuit is connected. An IC tag is disposed in the insulating layer and near the conductive pin. The IC tag has an IC chip and a coil antenna that is wound around the IC chip.

Igniter assembly, airbag system, and detection system and detection method for same

This igniter has a heating element, an ignition agent positioned so as to be in contact with the heating element, and conductive pins that pass through an insulating layer, and are electrically connected to the heating element. One end of each conductive pin is exposed through the insulating layer in such a manner that a current supply component, which supplies an ignition current, is connected to the heating element. An IC tag is positioned inside the insulating layer, in the vicinity of the conductive pins.

Igniter, igniter assembly, and detection system and detection method therefor

It is possible to feed an injection objective substance to a depth of a skin structure of an objective living body without using any injection needle. A syringe having no injection needle comprises an ignition device which includes an ignition charge containing a fuel component and an oxidizing agent component, a combustion chamber into which a combustion product produced by a reaction of the fuel component and the oxidizing agent component during combustion of the ignition charge is allowed to flow and which accommodates a gas generating agent that is combustible by the combustion product to generate a predetermined gas, and an enclosing unit which encloses the injection objective substance, wherein the injection objective substance enclosed in the enclosing unit is pressurized by a pressure in the combustion chamber in this construction. The fuel component and the oxidizing agent component contained in the ignition charge are determined so that any component, which behaves as a gas, is excluded from the combustion product when the combustion product is at ordinary temperature in the case where the fuel component and the oxidizing agent component are mixed at a stoichiometric ratio and combusted, and a cooling member is arranged in the combustion chamber so that the cooling member can be brought in contact with the combustion product produced by the combustion of the ignition charge to cool the combustion product.

The present invention provides a gas generator including:
